Abstract
A light emitting diode has a base made of heat conductive material, a wire plate made of an insulation material and secured to an upper surface of the base. Conductive patterns are secured to the wire plate, and a light emitting diode element is secured to the base at an exposed mounting area. The light emitting diode element is electrically connected to the conductive patterns.
Claims8
A light emitting diode comprising:
- a base made of heat conductive material and having a quadrangular shape;
- a wire plate made of an insulation material and secured to an upper surface of the base;
- exposing means for forming an exposed mounting area on the surface of the base;
- conductive patterns having anode and cathode patterns formed on the wire plate;
- a light emitting diode element having an anode and a cathode on an upper surface thereof and secured to the base at the exposed mounting area;
- and
- four lead wires for electrically connecting the light emitting diode element to the conductive patterns;
- wherein the wire plate has a same peripheral shape as the base, and
- the four lead wires connect respectively two parts of the anode and two parts of the cathode of the light emitting diode element to the conductive patterns further comprising four terminal portions formed at respective corners on the wire plate.
